Raman spectroscopy
www.chem.uci.eduFrom the Renishaw Raman software the user can select: • a fixed grating measurement with a spectrum 'window' of 400 cm-1 to 1000 cm (configuration dependent) • a unique 'extended scanning' facility allowing the user to choose any Raman shift range up to about 10000 cm-1 (configuration dependent). Essential for extended range
A Second Application of Symmetry
www.chem.uci.eduWe can use character tables to determine the symmetry of all 18 motions and then assign them to translation, rotation, or vibration. We can also tell which vibrations are IR or Raman active. Procedure: 1. Assign x,y,z coordinates to each atom. 2. Determine how each axis transforms for every class of symmetry operation in the group.

Compton Scattering - High Energy Physics
pages.hep.wisc.eduThe Compton effect is the elastic scattering of photons from electrons. As a reaction, the process is: γ +e −→ γ +e . Since this is a two body elastic scattering process, the angle of the scat-tered photon is completely correlated with the energy of the scattered photon by energy and momentum conservation. This relation is usually ...
